The Inverness chairman, Kenny Cameron, has criticised Rangers for taking the Scottish Football Association to court.
Rangers overturned their 12-month transfer embargo in the Court of Session on Tuesday after a judge ruled that an SFA panel had no right to impose the punishment under the governing body's rules.
Rangers could face more severe sanctions if the disrepute charge returns to an SFA appeal panel, with the stated punishments including suspension or expulsion from the game.
Fifa has urged the SFA to take "direct action" against Rangers for ignoring regulations prohibiting clubs from taking national associations to court.
Cameron told Inverness's website: "Taking sporting matters to the Court of Session was a serious mistake."
